WINDOW SASII PAINTBRUSII This invention relates to certain new and useful improvements in a special purpose painting brush which is such in construction and adaptability that it can be adjusted and handled, regardless of the angle of the brush in the hand of the user, to apply paint with expediency and ease and without haphazardly smearing unwanted paint on the panes of a window sash or panels of a door having an upper sashlike part.

Experience has shown that a sash brush constructed in accordance with the principles of the present invention is susceptible of practical and reliable use by an unskilled user. This is to say, repeated experience has shown that a steady hand is not required. Also experimental tests have shown that the brush and its accompanying handling means speeds up the job and saves valuable time and labor.

Briefly the ready-to-use device lends itself to unhampered painting of the surfaces of vertical mullions, horizontal dividers and restricted marginal sloping surfaces of component frame parts of a paneequipped sash. The bristled head is proportional in length and width with the limited surfaces which are to be brushed and painted. A suitable rigid head is operatively mounted at one transverse end of the bristled brush. This head is provided with a right angularly disposed shank which constitutes a component part of a brush mounting and an adjusting adapter. The adapter is cooperable with a manually grippable T-shaped handling and steadying unit or device in a manner to be hereinafter more clearly set forth.

One aspect of the invention has to do with a paintbrush characterized by the aforementioned bristled head. The free ends of the bristles are cut across at an angle oblique to the adjacent part of the handling unit or means. The head of the bristled brush may comprise a hollow sheath to accommodate a blocklike connector on a cooperating end of a screw-threaded shank which serves as the aforementioned adapter.

The handling unit or means is capable of being produced from lightweight metal or moldable plastic, as is generally the case. It is T-shaped in plan and has a suitably elongated handle with a crosshead at one end of the handle. One component part of the crosshead constitutes a fingerlike stabilizing and positioning guide. The other end portion of the crosshead has a screw-threaded hole for reception and adjustable mounting of the screwthreaded shank. A thumb nut is provided to maintain the brush adjustment desired.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIG. 1 is a fragmentary plan view of window sash showing mullions and dividers and showing, what is more significant, the improved sash painting brush and the manner in which it is constructed and used.

FIG. 2 is a view observing the structure of FIG. 1 in a direction from right to left.

FIG. 3 is a plan view of the overall ready-to-use device showing a portion broken away and appearing in section.

FIG. 4 is an end elevational view observing FIG. 3 in a direction from left to right.

And FIG. 5 is a perspective view of the composite or twopart paintbrush.

The part of the invention which is referred to as the special purpose brush is denoted by the numeral 6. The handling device or unit for the brush is denoted by the numeral 8.

The brush 6 comprises a bristled head of requisite width and length denoted by the numeral 10 in FIG. 5. The free ends of the brush bristles are cut across at an angle as denoted at 12. The complemental head at one transverse end of the bristled brush is denoted at 14 and as illustrated is preferably of hollow construction and provides a sheath 16 (FIG. 5). The sheath serves to accommodate the adapter means. More specifically the adapter means comprises a rigid block fixedly mounted on one end of a straight screw-threaded shank 18. The block is denoted at 20 and is fashioned to fit in the hollow portion 16 of the head 14 in an obvious manner to permit brushes to be changed and to permit brushes of different textures, if desired, to be used. 1

The plastic or equivalent holder or handling and steadying means 8 is of one piece construction T-shaped in plan and comprises an elongated handle 22 which embodies a plate portion 24 which is used to carry the trademark or other printed or equivalently applied indicia (not shown). This plate portion is marginally surrounded by an appropriate enclosing bead 26. There is a beaded hole 28 at the rearward end portion 30 and which can be employed to suspend or hang the tool from a nail, bracket or the like (not shown) when it is not being used or for other purposes. The outer or forward end of the handle 22 is provided with a crosshead 32. This crosshead is centered and one fingerlike end portion or extension 34 is rounded at 36 and constitutes a stabilizing guide and gauge which is disposed at right angles to the handle. The other oppositely extending end portion 38 is provided with a screwthreaded hole 40 into which the shank or adapter 18 is threadedly mounted and adjustably retained as is evident particularly from FIG. 3. The median portion of the shank is screwed through the hole and the extending end portion is provided with a thumb nut 42 which is used for adjusting and retaining purposes as is evident.

It is reiterated that the adjustable and detachable brush means 6 and handling means 8 coordinate in providing an assembly which, as repeated experience has shown, well serves the purposes desired. A steady hand is not required because the guide and gauge finger 34 rides on a coacting surface of the mullion or divider as is thought to be evident from the illustration appearing in FIGS. 1 and 2. Regardless of the angle of the brush in the painters hand it has been repeatedly proved that unwanted paint cannot and does not reach or touch the glass surface assuming, of course, that proper adjustment of the parts has been made prior to painting. When held in the hand and used in the manner illustrated in FIGS. 1 and 2 the brush is capable of being manually steadied and allows the painter to paint smoothly and with the brush bristles converting the entire surface desired without smearing unwanted paint on the coacting glass surface.

It will be noted that the bristled brush head 10 is in spaced parallel relation to the crosshead 32 and is in a generally com mon plane therewith. The mounting and adjusting shank or adapter 18 is offset from the lengthwise axis of the handle and is parallel thereto.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the. invention as claimed.
